No full textEmral, Ahmet Cihangir/0000-0003-3976-1387Objective: To evaluate the results of patients treated with fistulectomy and primary sphincteroplasty for uncomplicated perianal fistula. Study Design: Observational study. Place and Duration of the Study: Medicana International Hospital affiliated with Atilim University, Faculty of Medicine, Ankara, Turkiye, from January 2020 to September 2023. Methodology: In this study, patients who were operated on for perianal fistula between 2020 and 2023 were retrospectively examined. Data were obtained retrospectively. All patients underwent preoperative perianal MRI. Clinical notes were evaluated with the Cleveland Clinic Incontinence Score (CCIS) by physical examination. All patients were followed up on the first postoperative day, 1st week, 1st and 3rd postoperative months. Results: A total of 44 patients who underwent fistulectomy with primary sphincteroplasty were included in the study. Twenty-six patients (59.1%) had a history of perianal abscesses. It was observed that 34 (77.3%) of the patients had posterior, 7 (15.9%) anterior, and 3 (6.8%) lateral fistulas. A total of 3 patients (6.8%) were observed to have minor worsening in their incontinence scores. There was no statistically significant difference between the preoperative and postoperative 3rd month Cleveland Clinic Incontinence Score values of the patients (CCIS mean 1.6 vs. 1.7, respectively, p >0.05). Recurrence was observed in 1 patient (2.3%) during follow-ups. Conclusion: Fistulectomy with primary sphincteroplasty is an effective and reliable method to preserve anal continence and improve quality of life.Science Citation Index Expande
Hemoroid Lastik Band Ligasyonu Komplikasyonlarının Yönetimi: Masif Rektal Kanama
No full textAmaç: Çalışmanın amacı, hemoroidal hastalıkta cerrahi dışı tedavi seçeneklerinden biri olan lastik band ligasyonunu (RBL) ve buna bağlı gelişen komplikasyonları irdelemektir. Morbiditesi nedeniyle önem arz eden masif rektal kanama komplikasyonunun yönetimini sunmaktır. Gereç ve Yöntem: Evre 1-2 ve 3 internal hemoroidal hastalık nedeniyle 2018-2022 yılları arasında kliniğimizde RBL yapılan 564 hasta retrospektif olarak irdelenmiştir. Gebelik durumu, geçirilmiş anorektal cerrahi, kronik karaciğer hastalığı ve antikoagülan kullanımı nedeniyle 72 hasta çalışma dışında bırakılmıştır. Hastaların 492’si çalışmaya dahil edilmiştir. Tüm hastalara proktoloji ünitesinde detaylı anorektal muayene, 50 yaş üstündekilere ise kolonoskopik değerlendirme yapılmıştır. Hastaların demografik özellikleri, gelişen komplikasyonlar (minör/majör) ve uygulanan band ligasyon sayısı standardize edilmiş formlara kayıt edildi. Bulgular: Hastaların ortalama yaşı 33,4±11 (18-65) yıl olup, 385’i (%78,3) erkek, 107’si (%21,7) kadındı. Hastaların 39’una (%8) tek kadran, 448 hastaya (%91) iki kadran ve 5 hastaya üç kadran RBL uygulandı. RBL sonrası minör komplikasyonlar (anal ağrı, vazovagal semptomlar, minör rektal kanama, üriner retansiyon) yirmi hastada (%4) gelişirken, hastaların 4’ünde (%0,8) masif rektal kanama meydana gelmiştir. Masif rektal kanama gelişen hastaların hepsi acil şartlarda hospitalize edildi ve operasyona alındı. Bu hastaların birine 3 ünite, üç hastaya ise 4 ünite eritrosit transfüzyonu yapıldı. Sonuç: Hemoroidal band ligasyonu, hemoroidal hastalık tedavisinde güvenli ve etkili bir yöntemdir. Ancak hayatı tehdit edecek ciddi kanamalara yol açabileceği göz önünde bulundurulmalıdır
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Granulomatous mastitis, watch and wait is a good option.
No full textBackground Idiopathic granulomatous mastitis (IGM) is a benign and rare chronic inflammatory disease of the breast with unknown etiology. While there is no consensus regarding its post-diagnosis management, there are different treatment alternatives. Aims In this study, it was aimed to question the effectiveness of follow-up strategy without administering any treatment. Methods One hundred eighteen female patients diagnosed with IGM were retrospectively evaluated. Patients with histopathologically confirmed IGM were included in the study. Medical treatment was given only to patients who did not accept the follow-up option without treatment. The protocol used in steroid therapy was 16 mg prednisolone twice daily for 2 weeks, and then the dose was gradually reduced, and the treatment was stopped after 2 months. Patients were followed up with a physical examination every 3 months. The effectiveness of the systemic corticosteroid treatment and the follow-up approach without any treatment was compared. The recurrence rates and pre-treatment and post-treatment methods of the patients were examined. Results While 30.5% of the patients recovered with corticosteroid treatment, 42.4% recovered under observation without any treatment. The mean recovery period of the patients in these two groups was calculated as 3.9 months and 5.6 months, respectively. However, no statistically significant difference was found in terms of recovery period (p = 0.064). The recurrence rate was 11.9%. Conclusion For IGM, the "watch and wait" approach is an effective option. A chance should be given to the self-limiting nature of the disease with the addition of drainage when necessary
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Importance of Alkaline Phosphatase as a Predictor of Transient Hypoparathyroidism After Parathyroidectomy
No full textBackgroundThere are insufficient studies that have investigated the relationship between temporary hypoparathyroidism (hypoPTH) and the preoperative serum alkaline phosphatase (ALP) level in patients with no renal function disorder who have undergone isolated parathyroidectomy. The aim of this study was to determine whether or not the preoperative serum ALP level could be a marker which could predict the development of postoperative temporary hypoPTH. MethodsThis cross-sectional study included 158 patients aged > 18 years who were diagnosed with primary hyperparathyroidism (PHPT) between 2017 and 2022. The demographic data of the patients were retrieved from the hospital records. The patients were separated into two groups according to the serum calcium level after the parathyroidectomy, as the normal group and the temporary hypoPTH group. The determinants of temporary hypoPTH developing after parathyroidectomy in PHPT patients were investigated using multivariate logistic regression analysis. ResultsTemporary hypoPTH was determined in 25.3% of patients. The mean age and 25-O-HD level were determined to be lower in the patients who developed temporary hypoPTH compared to those who did not. The preoperative serum ALP, parathormone, and 24-h urine calcium levels were determined to be higher in the cases that developed temporary hypoPTH. As a result of the regression analysis, only the serum ALP level was determined to be an independent risk factor predicting the development of temporary hypoPTH (p: 0.005, OR: 1.021). In the ROC analysis, when a cutoff value of 119.5 pg/mL was taken for ALP, it was determined to have 73% sensitivity and 72% specificity for the prediction of the development of temporary hypoPTH. ConclusionsThe most appropriate treatment for symptomatic PHPT patients selected with positive imaging is minimally invasive parathyroidectomy. The most important postoperative complications are hypocalcemia and hypoPTH. The preoperative serum ALP level may be helpful in determining patients at risk of developing temporary hypoPTH following parathyroidectomy.Atilim UniversityThe authors would like to thank all the hospital staff who contributed to the publication of this article.Science Citation Index Expande
